Product details
Overview
PDTA143ZQB-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates 4.7 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), delivers −100 mV VCE(sat) at −10 mA/−0.5 mA drive, and supports automotive-grade operation per AEC-Q101 for load switching and IC input control.
For engineers reviewing the PDTA143ZQB-Q datasheet, PDTA143ZQB-Q pinout, PDTA143ZQB-Q application, or PDTA143ZQB-Q equivalent, key selection criteria include its built-in resistor ratio (R2/R1 = 10), −50 V VCEO, ultra-thin 0.48 mm profile, AOI-compatible side-wettable flanks, and qualification for automotive digital control circuits.
Technical Context
This PNP RET uses an integrated bipolar junction transistor with two monolithically embedded resistors to form a single-input, single-output digital switch. Its R1–R2 network sets base current and provides emitter feedback, eliminating external bias components while maintaining stable saturation under varying temperature and supply conditions.
The device operates with −50 V collector-emitter breakdown voltage and −100 mV saturation voltage at −10 mA output, enabling efficient low-side switching in 3.3 V and 5 V logic-controlled systems. Its thermal resistance of 298 K/W (on 70 µm FR4 PCB) supports sustained 100 mA operation within automotive ambient ranges (−40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive subsystems with margin. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, relays, and logic inputs. |
| VCE(sat) | −100 mV @ −10 mA/−0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Fixed internal bias network simplifies PCB layout and eliminates two external resistors. |
| R2/R1 Ratio | 10 - Optimized for predictable turn-on threshold and noise immunity in digital interface applications. |
| Tj max | 150 °C - Junction temperature limit supporting AEC-Q101 qualification and extended reliability in engine bay environments. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm leadless package with side-wettable flanks for automated optical inspection (AOI) and high-density routing. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, ultra-thin, leadless surface-mount package with side-wettable flanks for solder-joint inspection. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm body height; 0.65 mm pitch; 0.22 mm max flange height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level signal; internally connected to R1; defines turn-on threshold via VI(on) ≈ −0.9 V (typ). |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks up to −100 mA; connects to load between VCC and collector. |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive applications including body control modules and lighting drivers per stress test requirements. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield and traceability. |
| 0.48 mm profile | Ultra-low height supports ultra-thin end equipment such as ADAS sensors and compact infotainment displays. |
| −100 mV VCE(sat) | Reduces conduction loss to ≤1 mW at 10 mA, lowering thermal load in thermally constrained modules. |
Applications
| Automotive Lighting Control | Industrial I/O Expansion |
|---|---|
Use Scenario: Driving LED strings in interior dome lights and license plate lamps using 12 V battery supply.

Use Value: Built-in resistors eliminate need for discrete base biasing, reducing component count and enabling 0.65 mm pitch routing on 2-layer PCBs. |
Use Scenario: Level-shifting and buffering PLC digital outputs to 24 V field devices. IC Role / Device Role: Digital interface translator converting 3.3 V/5 V logic signals into robust 24 V sink outputs. Use Value: −50 V VCEO and AEC-Q101 rating ensure reliable operation in electrically noisy factory environments. |
| Consumer Appliance UI | Automotive Body Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143ZQB-Q | NPN complement with identical R1/R2 values (4.7 kΩ/47 kΩ), same package, but opposite polarity. | Requires inverted logic drive and high-side load configuration instead of low-side sinking. | Select when circuit topology mandates NPN sourcing or when sharing bias network design across complementary stages. |
| PDTA143XQB-Q | Same package and VCEO/IO, but R1 = 4.7 kΩ, R2 = 10 kΩ → R2/R1 = 2.13 (vs. 10 for PDTA143ZQB-Q). | Higher base current and lower input impedance; better suited for weak-drive MCUs but less noise-immune. | Prefer for legacy designs using BC857-Q alternatives where tighter VI(on) tolerance (−0.9 V vs. −0.6 V) is required. |
Compared with PDTC143ZQB-Q, PDTA143ZQB-Q provides true low-side sinking with matched automotive qualification; versus PDTA143XQB-Q, it trades higher noise immunity and sharper switching thresholds for reduced base drive sensitivity-critical in EMI-prone vehicle cabins.

FAQ
What is the maximum operating temperature for PDTA143ZQB-Q?
The device is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C. Its thermal resistance is 298 K/W on a 70 µm copper FR4 PCB, enabling full 100 mA output at +105 °C ambient when properly heatsinked via PCB copper pour.
Can PDTA143ZQB-Q replace BC857B-Q in existing designs?
Yes, as a direct functional replacement in digital switching roles: both are SOT323-packaged PNP transistors with AEC-Q101 qualification. PDTA143ZQB-Q adds integrated 4.7 kΩ/47 kΩ resistors, removing two external components while matching −50 V VCEO and −100 mA IO ratings.
How does the side-wettable flank design aid manufacturing?
The DFN1110D-3 package features exposed copper on the side edges of terminals 1 and 3, allowing automated optical inspection (AOI) systems to verify solder fillet formation without X-ray. This improves first-pass yield and reduces rework in high-volume automotive PCB assembly.
What is the typical VI(on) and VI(off) behavior across temperature?
VI(on) is −0.9 V (typ) at 25 °C and shifts to −0.6 V at 100 °C; VI(off) is −0.6 V (typ) at 25 °C and −0.5 V at 100 °C. This tight, predictable hysteresis ensures robust noise rejection in automotive CAN/LIN bus-adjacent circuits without external Schmitt triggers.
